l when ginned is blown upward and into the condenser box ll. When in v hleachlng eprollers should be removed from this it is desirable to have the lint cotton as loose as possible when subjected to the action oit the bleaching elements. From the hex B the lint is carried hy en endless apron C or other suitable convcyer to the bleaching ceptaele l) which it enters, preferably near the top es shown. This receptacle is me tangular and within it, the ends, are mounted lor rotation a series of rollers E that extend transversely troni-one side of the receptacle. to the other end in lwhich opposite sides they are jo'urnaled; these rollers are arranged in peirs horizontally, each )air carrying en' endless apron l? that travel iorizontally in the direction indicated by the darts. Any desired number of these aprons may be provided, all being arranged 'one above the other end spaced a sullicient distance apart to receive and convey the loose cotton Without compressing it. The `rollers lney be driven by `any suitable gearing or the like devices (not shown) causing each alternate apron to travel in nu o iposite direction.

Cotton lto be treated is deposited on the top apron near one end or' the receptacle sind is carried hy it. horizontally through. the

when it drops to the next apron W rich traveling in an opposite direction carries it beck to near the other end, when it again drops te the next succeeding apron and so on until it reaclnsthe bottoni apron `when it is delivn ered by it to condensing rollers G that compresses the cotton and delivers it through conductor El to the press box l,

rthe bleaching compound consists prefersimple method of burning the sulfur Vfind shows n common style ot l'urnitce and consists of an inverted tunnel shaped vessel conn taining a pen in which the sulfur is placed; when ignited it at once throws oit the desired tunic. which may he conducted through a hose li or otherniediuin to the bottom of the bleaching receptacle where it is shown connected at K' ln operation, sulfur containedn the nnece .l is ignited and the fume es generated 'core ducted through tube K and deposited within 5 the receptacle lgwhen the fume has ittl tained suilicient density the gine end other paratus is to be employed the condensieig4 length of the box to near the opposite end ,ably of fumes trom/.lmrning sulfur, and any generating the lnines in'ay be employed; J
